Job summary

Enphase Energy is seeking a Senior Manager, Mechanical Engineering to lead and scale the mechanical engineering function for SST racks, enclosures, and power module packaging. You will own mechanical architecture, drive designs from concept through production, and mentor a growing team of engineers in a fast-paced hardware program.

You will collaborate with power electronics, firmware, and quality teams to ensure EMI/EMC, thermal, and insulation requirements are met, while applying DFM/DFA

Qualifications

• Bachelor's degree in Mechanical Engineering or a closely related discipline; Master's degree preferred.
• 12+ years of experience in mechanical product design and development, with a strong track record across the full product development lifecycle.
• Demonstrated experience leading and managing mechanical engineering teams of 4 or more engineers, including performance management and career development.
• Significant experience in the mechanical design and integration of electrical support equipment for power electronics, power conversion, or analogous high-power electrical products — including busbars, wire harnesses, electronic board packaging, and connectors.
• Demonstrable expertise in design and manufacturing processes: injection molding, sheet metal fabrication, CNC machining, and stamping/die casting.
• High proficiency with an enterprise CAD package — SolidWorks strongly preferred, ideally in a PDM/EPDM-managed environment.
• Experience with DFM/DFA principles and close collaboration with contract manufacturers and fabrication vendors.
• Experience with both investigative and verification testing — including writing test plans, executing tests, and authoring technical reports.

Responsibilities

• Meet quarterly project progress targets, with goals that align with program milestones set by executive leadership.
• Lead professional development of your team — conduct performance reviews, support career growth, represent your team to the annual Performance Focal Group and Promotion Review Board.
• Own the mechanical architecture for SST racks, high-power enclosures, structural assemblies, power module packaging, busbar integration, and wiring harness routing. Drive designs from concept through detailed drawings, DFM review, and production release.
• Lead design options and reviews; drive optimization of electromechanical assemblies including EMI/EMC, thermal requirements, and electrical insulation coordination
• Apply DFM/DFA principles across the full product lifecycle, including supplier selection, process qualification, and tolerance analysis.
• Engage cross-functionally with power electronics, electrical hardware, firmware, systems, manufacturing, procurement, and quality teams to drive full-scope hardware delivery.
• Identify and resolve design requirement conflicts; ensure designs meet compliance requirements under UL, IEC, NEMA, and other applicable standards.
• Build and grow the mechanical engineering team — recruit, onboard, and develop top-tier mechanical engineers; establish team processes and a culture of engineering excellence and accountability.
• Present program status, technical risks, and design decisions clearly to senior leadership and cross-functional stakeholders.
